Safety

Contamination

What does the research say?

Traditional use

These are traditional uses, not proven treatments.

  • This patent medicine is based on Yin Qiao San, a formula from the classic Chinese text Analysis of Warm Diseases. It's a "cool" medicine used early in a feverish illness to expel "wind-heat", and treats fever, sore throat, headache and mild thirst. Its lead herbs are honeysuckle flower (jin yin hua) and forsythia fruit (lian qiao).[2]

Laboratory & animal research

Lab and animal results show what might be worth studying in people. They don't show that the herb has these effects in humans.

  • In lab studies, honeysuckle and forsythia extracts acted against flu viruses. In flu-infected mice, Yin Qiao San protected the lungs and reduced inflammation.[2]

Research in people

  • In a 2011 trial in 11 Chinese hospitals, 410 people aged 15 to 69 with mild H1N1 flu took the flu drug oseltamivir, a related 12-herb decoction (maxingshigan-yinqiaosan, which also contains ephedra), both, or nothing for 5 days. The decoction shortened the time to fever going away, as oseltamivir did. Participants knew which treatment they got, and the decoction isn't the same product as this pill.[3]

In short

A Hong Kong "Strong" version was recalled in 2014 for containing undeclared paracetamol.
